Body
I have a JavaScript object with some properties. Lets say: <pre><code>var haystack = { foo: {value: "fooooo"}, bar: {value: "baaaaa"} }; </code></pre> Now, I want to access one of those properties, but I don't know which one. Luckily, this variable does: <pre><code>var needle = "foo"; </code></pre> In modern browsers I seem to be able to do the following and it works: <pre><code>haystack[needle].value; # returns "fooooo" </code></pre> But in IE6 it throws a wobbly, <code>haystack[...] is null or not an object</code>. Is there a way to achieve what I'm trying to achieve in IE6? If so, how so? <hr> EDIT - Adding further information in response to the comments below... <hr> What I am trying to achieve is actually related to CKEditor. I haven written a plugin image manager that opens in an iframe. What I then want to achieve is to place the chosen image back in the correct instance of CKEditor (and there can be more than one instance on some pages). What I have done (and I know this is an ugly hack), when the iframe is opened I have put a hidden field next to it with the name of the instance. So the parent page contains some markup like this: <pre><code><iframe></iframe> <input type="hidden" id="ckinstance" value="article_body" /> </code></pre> So then, inside the iframe when an image is selected to be inserted I have some JavaScript that looks like this: <pre><code>var CKEDITOR = window.parent.CKEDITOR; var instance = window.parent.$('#ckinstance').val(); var img = '<img src="/whatevers/been/selected" />'; CKEDITOR.instances[instance].insertHtml(img); window.parent.$.modal.close(); </code></pre> This works fine in FF, Chrome, etc. Just IE6 is complaining with: <pre><code>CKEDITOR.instances[...] is null or not an object. </code></pre> EDIT 2 I've just done some debugging and actually it looks like IE6 is failing on <code>window.parent.$('#ckinstance').val()</code> and is returning undefined. So the original problem that I've described is not the problem at all. Still need help though :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
